Schaller S-Locks

In 1981, Schaller developed and got the patent for a totally new category of product, which revolutionized the connection between guitar and strap. With its unique design and functionality, Schaller has been setting the standard in strap locks for decades.
 
In 2018, Schaller will pave the way for the next generation of revolutionary strap locks. These new S-Locks are silent. They feature one-piece hardened steel strap buttons, aesthetic design, perfect handling, an elegant Lock-Wheel and all former hiccups have been tackled!

Hardened steel and more than double thickness of the strap button guarantees maximum security against breakage.
Including high-grade felt washers for ultimate protection of guitar's finish.
Extended thread length for holding straps of up to 6 mm thickness.  
New designed slanted locking bolt in stainless steel for permanent precision, reliable performance and wear-free finish.
